Trả lời
The correct answers are:<br /><br />1. **don't stop** The sentence requires the negative form of the present simple tense to create a first conditional structure. "If we *don't stop* damaging their homes, there will be fewer birds."<br /><br />2. **will die** This uses the future simple tense in the result clause of the first conditional. "If we don't clean up the river, the fish *will die*."<br /><br />3. **will save** Again, future simple in the result clause. "If we turn off the air conditioner, we *will save* electricity."<br /><br />4. **will be** Future simple in the result clause. "If you throw trash on the beach, it *will be* polluted."<br /><br />5. **ride** Present simple in the 'if' clause. "We will save the environment if we *ride* our bikes to school."<br /><br />6. **will have** Future simple in the result clause. "If we keep the air clean, we *will have* fresh air to breathe."<br /><br />7. **keep** Present simple in the 'if' clause. "We won't stop land pollution if we *keep* using too much plastic."<br /><br />8. **will damage** Future simple in the result clause. "If we don't stop polluting the air, we *will damage* the environment."<br /><br />9. **will happen** Future simple in the result clause. "What *will happen* if we don't do anything to lower pollution?"<br /><br />10. **won't affect** The sentence requires the negative form of the future simple tense. "It *won't affect* the wildlife if we keep the rivers and seas clean."<br /><br /><br />The multiple choice options provided (A, B, C, D) for question 1 are incorrect and irrelevant to the sentence structure needed. The question requires a verb in the negative present simple tense.<br />
